Possibly. But perhaps the spec.s are off for one or both rep.s..

They are at least very similar, and should work reasonably well as a open baffle helper woofer in the context that Martin presented.

For a product with such a use, price is the major factor.. and I'd suspect that shipping costs would play a large roll in determining it's relative value.

I believe the QTS for the 1850 is .67 so this is a lot different than the 1.07 for the
1858.
